Radiology of bone lacunae can help differentiate between smouldering and symptomatic myeloma. CT seems to be more apt for this purpose than a standard X-ray but appropriate principles must be applied when performing and reading it. Lesions visible in an MRI above all allow myelomas to be monitored during treatment. Because of the radiation dose, whole body CT must be performed with a slice thickness of 2 mm, increments of 1.5 and intensity of 40 mAs. It should be read associating the reading of the axial slices with reading the mean coronal and sagittal projections of a thickness of 2 cm. Whole body MRI must associate T1-weighted sagittal, STIR coronal and b-800 diffusion-weighted axial sequences. Changes in the disease correlate with changes in the diffusion, STIR and T1-weighted images interpreted together. While whole body CT has a place in clinical routine, the indication for whole body MRI still needs to be clarified and has yet to take its place in research protocols. © 2012 Éditions françaises de radiologie.
